DoDataExchange doesn't like pointers ?
-
If I declare a CEdit dynamically in my dialog file and try to connect the resource id of editbox to it via DDX_Control(IDC_EDIT_BOX, *pEdit); The program asserts. It works fine if I create a CEdit object on stack and pass it. Why is it that DoDataExchange doesnt work as expected with dynamically allocated variables ? I thought I knew Intermediate level MFC before this one stumped me :( Thanks Cage

Why? I.e. what was the assertion message?

This is going on my arrogant assumptions. You may have a superb reason why I'm completely wrong. -- Iain Clarke -

Are you creating the
CEditobject and callingCreate()before or after callingCDialog::OnInitDialog()?"Love people and use things, not love things and use people." - Unknown

It was not a yes/no question.

It's required. Now, where is the call to
CDialog::OnInitDialog()in relation to where theCEditobject is created and itsCreate()method called?"Love people and use things, not love things and use people." - Unknown

Do you want to make dynamic editbox and use of their events?

I don't think so david. I am pretty sure I don't need an explicit create call in my oninitdialog if I am linking the editbox with the dialog with DDX_Control call. As it turned out, it was an issue with the resource ID.Thanks for the advice though. Regards Cage

Correct. But the
CEditobject must be created beforeCDialog::OnInitDialog()is called. Otherwise,DDX_Control()will throw an exception."Love people and use things, not love things and use people." - Unknown
